FALL-ROPE CARRIER.-

Carrier for Conveyers or Cableway's, of which the following is a full, clear, and exact descj'tion.

rope-carrier which is sim ler and less liable to derangement than any eretofore known or used. In eonveyers of this character it is desirable and necessary to sup ortsome or all of the flexible ropes employs from the main cable or trackway, .so as to prevent sagging and interruption to the successful movement raising and lowering of the load or bucket from the load-carriage at any point between Each carrier is auto matically movable at a predetermined and characteristic relative rate, so as to maintain sive carriers. To attain this object, each carrier is provided with a single propelling element, like a grooved wheel or pulley. This wheel or element preferably engages the under side of the main track or cable and the upper side of the endless haul-rope. The track, the wheel, and the haul-rope are in one and the same vert cal plane, and the resultant into engagementiwith the main track. This steadies the carrier and prevents wabbling. With a grooved wheel of any given diameter the rate of advance-movement is one-half the speed of the haul-rope. To secure an increased speed of movement, the single wheel is irovided with two peripheral contacts at di erent radial points. The haul-rope,- of' smaller diameter th'anthe :mainytrackor cable, engages the wheell; at;the'shorter radial distance, and theme-in cable engages the wheel at the greater radial distance. TOIPIOT vide these two peripheral contacts, a deeper groove bisects the circumferential groove,

less diameter engages the peripheral contact at the shorter radial distance.

This improvement also provides means to insure an effective yet a yielding engagement Specification of Letters Patent.

' This specification is a specific descri tion of one form of the invention, while the e aims are definitions of the actual scope thereof.

Reference is 'to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in. all the and ' figures.

Figure 1 shows in general elevation an overhead conv'eyer system having these improvements applied thereto. Fig. 2 is an enlarged side view of a cable-carri er. Fig. 3 is acorresponding end view thereof. Fig. 4 is a detail view showing one mounting for the traction-roller. Fig. 5 is an enlarged side view of a propelling-wheel having an increased speed of movement as compared with that'shown in Fig. 2, and Fig. 6 is an end view of the device shown in Fig.

In Fig. 1, 10 and 11, respectively, indicate the head and tail towers or sup orts for a main track or cable 12. The hau =rope or traverse-rope is shown at 14.. It is, in effect, endless and has one or more turns round the winding-drum 1 5. The fall-rope 16, oper-- ated by the drum 17, supplies'the means for raising and lowering the load with resp'ect'to the load-carriage 18. i This fall'rope 16, as shown in Fig. 1, is fixed at one end 30 to the tail-tower 11. It passes over the carrying Referring to Figs. 2 and 3, the fall-rope carrier is constructed'with a frame 19, which may be of any suitable material, preferably consisting of iron cheek-plates, between which pass the cable l-2 -j'and the lower run of the haul-rope 14. These cheek-plates are secured by angle-pieces 29 and each anglepiece held in position bya bolt. In the lower part of therope-carrier is a sheave or guide 20 for the fall-rope 16, and mounted in the upper-part are two' ca rrier-wheels 21 21, that run on the main cable 12 to support the ropecarrier. The haul-rope 14 runs over two sheaves 22 22, mounted in the frame and suitably spaced with respect to each other. The broad wheel-basc, due to the location of the sheaves 21 21 in vertical planes separated a distance about equal to a diameter of. the driving element 23 causes the carrier to maintain a vertical position. This is rendered still more stable by the similar location. of the sheaves 22 22. The position of the rotary driving element 23 with respect to the two pairs of sheaves 21 and. 22 is such that the traclecable 12 is pinched between the sheaves 21 and the driving element. This all contributes to the stability of vertical position.

Located within the frame of the rope-carrier is the free traction-roller, pulley, wheel, or driving member 23, which bears between the main cable on one side and the haul-rope on the other and lies in a vertical plane, in

which are also the main track 12 and the haulrope 14, engaging the wheel 23-at opposite ends of a diameter. The sheaves 21 and the sheaves 22 are also in the same plane and serve to pinch the cable 12 and the haul-rope 1 1 into engagement with the wheel In the form shown in Fig. 2 the Wheel 23 is free without pin or axle. The form and disposition of the parts 12, 14, 20, 21,22, and 23 are so regulated that both cables will bear tightly against the roller 23, the haul-rope being sprung or bowed slightly at the opposite sides of the traction-roller. This causes the actuating-rope (in this instance the haul- 'rope) to press the traction-roller upward against the main cable, and thus maintain a firm yet thoroughly elastic engagement between the parts 12 and 23 and 1-1 and 23. in effect, the free roller or wheel 23 isgripped between two cables. By this arrangement it will be seen that the parts are engaged with that firmness essential to the most successful operation of the carrier, as will be hereinafter fully set fo th; but we avoid that unyielding contact heretofore involved in'this class of apparatus, which operates to waste power by the excessive friction and to cause the working parts to quickly wear away, and we also avoid spring-contacts. With this apparatus as the haul-rope'rnoves at'a certain rate; of speed it imparts a rotary movement to the traction-roller or driving member 23, causing the roller to run along the stationary main cable, while the rope-carrier is advanced at a lower speed than that of the haul-rope 14.

As shown in Figs. 2 and 3, the rope-carrier will run on the main cable at one-half the speed of the haul-rope, because the same diameter contacts with both the stationary cable 12 and moving rope 14. The rope-carrier will be made to shift its position along the main track following the shifting position of the load-carriage, but at one-half the speed thereof. Fig. 2 shows the roller simply as a floating element without pin or axle confined endwise of the carrier by the bend of moving rope 14. In Fig. 4 wheel 23 on a pin or axle 24, which plays in vertical slots 25, formed in the cheek-plates constituting the frame of the carrier. This allows the traction-roller to yield vertically toward and from the cables 12 or 14, so as to assume a position insuring that uniform engagement between the rollers and cable above explained. It leaves the roller free to move slightly upward, and this enables: the haul-rope to press the roller more effectively into frictional engagement'with the main track 12. It is clear that by varying the relative distances of the ropes l2 and 14 from the center of the tractionroller-that is, by, providing pe ripheral contact points or surfaces at respectively different radial points-the speed at which the rope-carrier is propelled with :espect to the movement of the haul-rope 14 may be varied at pleasure. Figs. 5 and 6 show an arrangement by which the rope-carrier is made to run at three-quarters the speed of the haulrope. This is attained by pro viding asingle traction wheel or roller having two peripheral contact-points at different radial distances, shown at 2b and 27, respectively, the pmipl'ieral contact 2o being on the shorter radiusand the peripheral contact 27 being on the greater radius. The haulrope 14 engages the shorter radial periphery 26, while the main cable 12 engages the longer radial periphery 27. The sheaves- 20 21 22 are disposed the same as before described, and the action of the parts is the same, except that by varying the radial'distance of the peripheral contacts, as above explained, the speed is varied. in Fig. 5 openings 28 for the adjustment of the sheaves 22 are shown, as also in Fig. 2. i

The traction-roller shown in Figs' 5 and 6 is best shown in detail in Fig. 6, the construction including the shorter radial peri iihery 26 between two annular flanges extending beyond the periphery 26 to form the greater radial periphery 27. The haul-rope 14 being smaller than the plain cableruns between these flange-like portions and bears on the periphery 26, while the main cable 12 runs upon the outer edges of the said flanges.

In connection with the invention as above described it is pointed out that the employ ment of a single propelling-wl'ieel 23 provides for maintaining the'elements 12, 14, and 23 in the same vertical plane and accurately balancing the rope-carrier thereon, thus avoi ling the side lash or wabbling of the carrier, since the pressure between the parts is in the same plane and'central of the carrier.

Various changes in the form, proportion, and details of this invention may be resorted to without departing from the spirit and scope thereof.
